METHOD AND APPARATUS FOR CODING VIDEO HAVING TEMPORAL SCALABILITY, AND METHOD AND APPARATUS FOR DECODING VIDEO HAVING TEMPORAL SCALABILITY

摘要

Provided are a video encoding method and apparatus having temporal scalability, and a video decoding method and apparatus having temporal scalability. The video encoding method includes: splitting pictures included in a picture sequence into 5 temporal sub-layers; classifying a temporal layer access picture as a first temporal layer access picture or a second temporal layer access picture based on whether a picture, which is encoded after the temporal layer access picture and belongs to a same or upper temporal sub-layer as or than the temporal layer access picture, is capable of referring to a picture encoded before the temporal layer access picture; and adding type o syntax information for identifying the first temporal layer access picture and the second temporal layer access picture to transmission unit data including the temporal layer access picture.
